Intelligent dewaxing and dewatering purification device

Abstract

The invention discloses an intelligent dewaxing and dewatering purification device which comprises a reaction kettle body, a horizontally-arranged net plate is welded to the inner wall of the reaction kettle body, protection plates distributed at equal intervals are welded to the bottom end of the net plate, and second fans distributed at equal intervals are welded to the inner wall of the reaction kettle body. Two steam heaters are welded to the inner wall of the reaction kettle body, the height of the top ends of the steam heaters is larger than that of the top end of the second fan, an obliquely-arranged flow guide plate is welded to the inner wall of the reaction kettle body, a flow guide hole is formed in one side of the outer wall of the top of the flow guide plate, and the flow guide plate is located at the bottom of the second fan. Flow guide pipes which are distributed in a zigzag manner are welded on the inner wall of the reaction kettle body. According to the invention, wax can be fully heated, so that water in the wax is fully evaporated, the water removal efficiency is improved, hot air in the reaction kettle body can be recycled, heat loss is reduced, and the device is energy-saving, environment-friendly and high in intelligent degree.

Description

technical field [0001] The invention relates to the technical field of dewaxing, in particular to an intelligent dewaxing water removal and purification device. Background technique [0002] At present, in the investment casting industry, wax needs to be recycled many times. The investment casting first needs to make a wax mold, and then make a mold shell. After the mold shell is dried, put the mold shell in a dewaxing reaction kettle to pass water The wax is removed from the mold shell, and the steam guide valve is always open during the whole dewaxing process, so that a large amount of condensed water will be produced to merge with the wax, and the zirconium sand on the mold shell will fall off and be mixed with the wax. If it is reused , the moisture and other impurities in the wax must be separated; the commonly used method is steam heating, but it is easy to mix water into it when steam heating. [0003] After retrieval, Chinese Patent No. CN 206276869 U discloses an i...
